' TRAFFIC-SIGNAL APPARATUS. i

v Application filed April 26,1924. ,y Serial No. 709,148.,

veniently actuated whereby to control or' regulate'the traffic on streets, railway crossingsor other' tlioroughi'ares.

Further, said invention has for its object to provide an apparatus of the character specilied in which the signal or 'sound producing means is actuatedby a suitable operating Huid; the iiow ot' which from its source 0i' supply to said signal or sound producing means is manually controlled by the' traffic oiiicer or operator.

Further, said invention has for its object to provide an apparatus of the character specified in which the container or receptacle for the operating iiuid serves as -abase 0n which theV signal sound producing means and the control therefor are mounted..

Further, said invention has for its object to provide an apparatus of thel character speciiied in which one form of valve actuating means may be readily substituted for another in order easily to adapt the apparatus for use under varying conditions oiu-se.

Further, said invention has for its object to provide an apparatus of the character described in which the signal or sound producing device, and the means for controlling the operation thereotl are composed of two essential parts which are so constructed and arraiigedthat said'parts may be readily detached rom'each other, and a Adifferent form of controlling means substituted in'place of the one removed. y i

@ther objects will in vpart beobvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects 'and ends, my invention consists in the ynovel features of construction, and inthe combination, connection and arrangement of. parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings showing an illustrative embodiment of the invention,

Figure 1 is an elevation showing one form of apparatus constructed according to and embodyiiigmy said invention; l i

Fig. 2 is a vertical sectional View on the line 2-2 of Fig. 1; l

v Fig. 3 is a transverse sectional view on the line 3--3 of Fig. 2, and

p Fig. 4 is an elevation showing a modified form of apparatus with parts broken away and in section.

In said drawings 10 designates a receptacle or'tank provided with an inlet 11 through 60l which air or any other suitable operating fluid may be introduced, and maintained under pressure therein. rlhe tank 10 has avv substantially flat base 12 on which the apparatus may rest when in position upon a c5 support, which may be rthe .surface of the street or other desirable base. n

A tubular member 13 is secured in the top of the tanlrlO to communicate therewith, and projects upwardly therefrom. The member 13 is provided withv a-valve seat litlierein with which a movable valve member 15 cooperates. A valve.' stem 16 extends partly above and below said valve member 15 through the perforate guiding members or spiders 17, 17a which .serve to center and guide the stem 16 in" its movement therein.v The member 17a is'disposed within the upper portion 18 of the tubular member 13 which is threaded. fzlhe upper end oi" the stem 16 is 80 provided with a head 19 vlocated abovethe `upper end of member 13. A spring 2O is interposed betweenthe guiding member 17a andv y(the head 19 to maintain the valve member 15.

normally seated or closed.

, p 85 The tubular member 13 is adapted to receive either the tubular extension 21 (Figs. 1` and 2), or the tubular extension 21a (Fig.

said extensions being secured within kthe threaded kend portion 18 ot the member 13.

Theextension 21f has a downwardly extending bracket 22 at one vside thereof. A

valve actuating member or lever 23 is pivoted at one end 21i'to Vthe bracket 22, and extends transversely through the slots`25 in the ex- 95 tension 21 over thev head 19 of the stem 16,

and is provided at its oppositeend with aiinger piece 26 for depressing the same. If de here shown as a Whistle 29 adapted to be actuated by the fluid in its passage When the ifree end of the lever 23 is depressed.

In `Fig. l the valve actuating means consists oi a lever 23"L pivoted at one end to the 'upper end oi' an upivard-ly extending bracket 22 which projects above the upper end of the tubular extension 21a. The arin 23a extends Itransversely across the top of extension 21a and is provided at'its r'free end Wit-h an actuating chain 27, rlChe rod 30 is pivoted at its upper end 31 to the cent-ral portion of the arm 23, and extends downwardly through the upper end of the extension 21, and is provided. at its inner end With a head 32 which engages the head 19 on the stein 16. v30 is guided and centered by means of a sleeve 33, and by means of the end oil said extension 21a throughv'hich it slides.` `When the chain 27 is drawn downwardly the lever 232L depresses the rod 30 and opens the valve 15.

lt Will be noted that each valve actuating means illustrated i-s arranged to become operatively associated lwith 'the head 19 when either extension 21, 21a carrying the same is .secured in positionV on the tubular member 13.

Each extension 21, 21a may be removed Without requiring additional manipulation to disconnect the actuating means carried thereby from the valve stem 16. rllhis feature permits Tof the use of the apparatus under the varying conditions and as the requirements of operators may render more convenient or desirable.

The apparatus being` a complete unit is also portable to permit of the same beingeasily and conveniently moved from place to place. f The actuating lluid, Which is preferably air, may becompressed Within the receptacle or tank 10 either by a hand pump or a motor driven pump. When it is desired to actuate the signal device orvvhistle 29, the oi'iicer or operator depresses the lever 23 (Figs. 1 and 2) vvhicli opens the valve land permits the passage of air trom taiilr 1G through the members 13 and 21,. and into the lvfhistle29 to actuate the same. \l7heui theflever 23 is released, the spring 2O returns the valve to closed position. In like mannenivhen the rod 30 (Fig. 4) is depressed by the drawing down lof the chain 272l 'the valve 15 Will be opened and the air caused to enter the Whistle and aetuate the saine. The valve 15 is closed by spring 20 when the chain 27a is released.

Having thus described my said invention, what l claim and desire to secure by Letters Patent is 1. kiApparatus" 'of the vcharacter ldescribed comprising a receptacle adapted to hold an operating fluid under pressure therein, a tubular member having an end in communication with said receptacle, said tubular member having va valve seat therein, a valve'stem guide disposed adjacent the other end of said tubular member, a valve and a valve stem disposed Within said tubular member, said stem projecting beyond said other end, a second tubu- Vlarm'ember disposed in alignment with said .first mentioned tubular member and detachably secured to-said other endand into Which` said valvey stem projects, a valve operatingk ldevice, carried by said second tubular member, aivhistle also carried by said second tubu-V lar member, said valve operating device including a member located partly Within` and partly outside of said second tubular member, that part ot said device Which is Within said second tubular member being arranged to engage the projecting end 'of said valve stem, and a spring on said stem all being arranged whereby said first tubular member, said Valve,

- said valve seat and said spring constitute one unit, ano said second tubular member, said Whistle and said valve operating device constitute asecond unit, said tubular vmembers having separable connection one With the other for the purposes described. i

2, Ain apparatus of the charac-ter described comprising a receptacle to contain an operati ng fluid under pressure, a first pipe one end of Which is secured 'to and in communication with said receptacle, theother end of' which. has one element of a detachable oint, a valve seat Within said pipe, a valve associated with said seat, a valve stem and a valve stem guide,

combnedwith a secondv pipe one endet `which has the other end of the detachable c joint, a valve operating elem-ent mounted on said second pipe and in part located Within the same, a Whistle on said second pipe, said valve stein projecting into said 'second pipe when said joint `elements are assembled and engaging With said valve operating element,

all beine' arranged substantially fas and for"- the purposes described..
